- Q: What are the chemical reaction conditions in organic chemistry are catalyst and heating, please elaborate
- This really does not have omnipotent law, their own more than one point, you can classify to remember, when I was in high school is in accordance with the notes, such as poly, polycondensation and the like. In general, the double triple bond addition, plus halogen is not the conditions, plus HCl, HBr and the like to heat; dehydration reaction generally concentrated H2SO4 heating, dehydration condensation is also; there are some special, such as ethylene added to ethanol Special temperature requirements, it seems that 120 degrees, there are other; other addition poly, polycondensation some need catalyst. The The In short, the conditions are many, in general, you do not go to the high school to do more questions after the feeling, encounter problems do not panic general experience can come out according to experience, this also depends on the usual accumulation, if the equation conditions Wrong to deduct points, it is not worthwhile. There are some questions when the examination will give you some information, whether you know do not know should see clearly, although some of the reaction but the subject to the conditions are not the same, when you do according to the title to write conditions, this will not wrong. In addition, thank you for your help, I do not seem to know you
- Q: What is the difference between biological enzymes and chemical catalysts?
- Biological enzymes are an environmentally friendly biocatalyst with greater superiority. Such as the reaction speed, processing conditions (such as temperature, PH value, etc.) more moderate, safe and easy to control the operation and can replace the strong alkali and other chemicals. The biological enzymes act only on specific substrates, with little damage to the substrate and the biodegradation of the treated wastewater to reduce water and energy consumption. After more than a century of research by scientists, more than 3,000 known enzymes are generally considered. The application of biological enzymes in the textile industry, initially the application of α-amylase in cotton fabric desizing process, and later developed into the cellulase used in denim washing and bio-polishing process, and now the development of pectinase to the biological scouring Technology, hydrogen peroxide enzyme catalytic decomposition technology, protease in silk and wool fiber applications
- Q: Horseradish enzyme catalyzed Luminol chemiluminescence reaction
- Disinfectant ah ~ bleach ah ~ ~ take this kind of thing to wash the blood once something can interfere with Lumino identification. So that want to do bad things must be a good plan. Lumino in the presence of copper, copper alloy, horseradish or some bleach in the presence of fluorescence. So if the scene of the crime was bleached
- Q: okay im doing a project for my classroom about catalyst and i have to draw a picture but when i looked up on google i just saw a bunch of random stuff and a couple were metal so thats why im asking this question. :)
- A catalyst is something that enables a process to take place without being part of said process itself, such as in a chemical reaction.
- Q: What is the difference between biological and chemical catalysts?
- Biological catalysis involves an enzyme usually working in conjunction with a co-enzyme. These enzyme/co-enzyme systems are highly specific and are usually only effective for one reaction. Catalysis of non biological reactions is usually much more general and any one catalyst will be effective in many reactions.
- Q: give an example of how a catalysts speeds up the rate of reaction?? thank you!!?
- I like the hydrogen peroxide answer, but I just ran out of MnO2 at my house, I guess I will just have to pour some H2O2 into the small cut I have. The bubbles you see are oxygen gas which is formed by the decomposition of the H2O2 catalyzed by the peroxidase enzyme in your blood.
- Q: What is the analytical principle of chemical adsorbents? How about the number of active catalyst centers tested?
- What do you mean by the chemical adsorber? BET is the use of the surface of the uneven force field, but the inert gas at low temperature in the surface adsorption. TPD, TPR is the number of active centers that can be measured by the technique of desorption and reduction between specific gases and catalysts as the temperature increases. If the active site is a reduced position, H2-TPR can be used. If the active site is acidic, NH3-TPD can be used, but also the method of alkali titration.
- Q: In biology, the enzyme seems to be a tool for opening a reaction, such as the decomposition of cellulose, such as linked RNA and protein, no enzyme can not. But in chemistry, the catalyst is only a regulatory role, change the reaction rate only. The teacher said that the enzyme is the catalyst. Is there any other effect of the enzyme? (Ignorant high three dogs, you do not spray the big god)
- I do not know the main high school teachers have done with fresh chicken liver grinding solution and ferric chloride solution compared to the decomposition of H2O2 catalytic efficiency of the experiment, the result is ferric chloride plus H2O2 slowly take the bubble, add fresh chicken cups Quickly take bubbles and liquid spill. Indicating that the enzyme is a catalyst, and the catalytic efficiency is far higher than the inorganic catalyst.
- Q: chemistry subject
- Catalyst is the substance used to enhance or reduce the speed of a reaction.. there are thousand of catalyst used..(product of one reaction may act as catalyst of another).. you can see in google
- Q: Why would the Eact decrease if a catalyst is added?
- Catalysts work by providing an (alternative) mechanism involving a different transition state and lower activation energy. The effect of this is that more molecular collisions have the energy needed to reach the transition state. Hence, catalysts can perform reactions that, albeit thermodynamically feasible, would not run without the presence of a catalyst, or perform them much faster, more specific, or at lower temperatures. This can be observed on a Boltzmann distribution and energy profile diagram. This means that catalysts reduce the amount of energy needed to start a chemical reaction.
